Answer:
x=31
y=6
Step-by-step explanation:
2x+3y=80
x+y=37
solve by elimination:( multiply second equation by 2) to eliminate x
2x+3y=80
2x+2y=74
subtract the two equations:
2x+3y-(3x+2y)=80-74
2x+3y-3x-2y=6
y=6 (3 point basket)
substitute: x+y=37, x=37-6=31
x=31 (2 point shot)
Answer:
Step-by-step explanation:
If the Number of Sales of x units, N(x) is defined by the function:
Next, we text the critical points and the end points of the interval to see where the derivative is increasing.
Thus, the rate of change of sales 
is increasing in the interval on 10≤x≤40.
